Deploy the symatec over through ISA and ASA

ear Experts,
I have one server it has two nic card External interface it is directly connected with an ASA firewall and then the internal interface is directly connected with one switch(SW1 for ur identification) under the switch the two system directly connected.We took one connection from this switch and connected with another one ASA firewall E0 the E0 ip is 192.168.4.1 the E1 ip is 192.168.1.1 the E1 interface directly connected with one switch (SW2 for your identification) under the switch five system directly connected each system has same subnet of the E1 interface as well as those system keep on the gateway ip address of interface E1.what process going on here the two system under connected with SW1 it has one FTP-SSH Software the two system ip is 192.168.4.11 and 192.168.4.12 the 192.168.1.0 network get the data from 192.168.4.11 system through this ftp-ssh software cross over the ASA2 firewall , The ASA firewall has two rules source :192.168.1.0/24 Dest:192.168.4.0/24 Trafic:Incoming Interface:Internal Services;IP
The second one is source:192.168.4.0/24 Dest:192.168.1.0/24 Traffic:Outgoing Interface:Internal
Services:IP
these two rules are available in the ASA firewall.if i want to deploy the symantec i want to open the port out side tcp port 1024-5000 when ever the symantec server like to contact with client it should be running on this port no so i wnat to open the port no in out side
